Evolution of an idea

Most of this winter, work on 118 Henry Street was all about energy efficiency. Though not very photogenic, and certainly not glamorous, the results of stopping air infiltration, adding insulation, and improving the thermal boundaries have not only paid off monetarily, but, have also made a conspicuous improvement in our winter comfort level.

The general philosophy of stopping air infiltration is plug the air holes from largest to smallest, from upper stories to lower stories. The largest of our air holes were 3 “closets” that were doors opening up directly into the attic space.  See here for the closet in the west upstairs bedroom.

The second of these unmanaged thermal boundaries was behind a door on the stairs landing. This space is partially under the new metal roof and was insulated last spring. See here.

Unfortunately, there was still tremendous air exchange between inside the house and the attic.

The space was oddly shaped and really didn’t make a very good storage closet so we decided to turn it into a server closet for our henrystreet.net network equipment.

Looking in to the attic space before


In progress, thermal barrier in place


All the walls and the ceiling are insulated with fiberglass insulation, all the cracks and holes are sealed with caulk or expanding foam. The wiring boxes have foam rubber inserts to seal around the wires going thru the wall.

Pretty much done and in use


Odd shot of servers, networking equipment, and attic access


As part of this work, Howard, Carole’s son, and I re-ran all the network and cable TV wiring for the entire house.  Originally, I had wired the house and terminated it in the crawlspace. The re-wire was 2 days worth of work that paid off big for the extra convenience of having all the equipment easily accessible.

Oh, and by the way, we plugged the big air hole.
